Snares

SNAREs

receptors for sNAPs. The neuronal receptor for vesicle SNAPs, v sNARE, is synaptobrevin, also called vAMP 2. The target (t SNARE) associated with the plasma membrane of the axonal terminal is syntaxin. The SNAP SNARE complex is apparently responsible for regulating vesicle targeting: neurotoxins such as tetanus toxin and botulinum toxin selectively cleave sNAREs or SNAPs.

cellular component

... size and by how it forms (through the formation of a clathrin/COP/caveolin coat), and also through the presence of some surface proteins like v-SNAREs A vacuole is the plant (and yeast, and some protozoan) equivalent of an animal cell lysosome. Animal cells don't have vacuoles and plant cells ...

Molecular Cell Biology

There would be no vesicular trafficking going on in the cell then, as SNAREs are used to mediate membrane fusion. Think about what goes on basically in the Golgi complex. Can this organelle be able to do its function without SNARES?

If the v-SNAREs were missing in a cell, what would happen? :roll:

Calcium ions

... not only; some SNARE interactions are also involved, but they are not at their full capacity). There is a protein(synaptotagmin) that binds the SNAREs and does not allow them to fully interact, thereby precluding membrane fusion. Calcium binds to synaptotagmin and causes a conformational change ...
